Little Johnny has questions for his mother.
The first thing he asks is, “How old are you?” His mother says, “It’s impolite to ask a lady how old she is.” He then asks, “How much do you weigh?” to which she says, “Johnny, that’s impolite too!” He asks, “Why did Dad leave?” His mother sighs, and says, “I don’t want to talk about that.” Unsatisfied with her answers, Little Johnny ran off. He returns five minutes later holding her license. “Mommy, I figured it out! You’re 35, you weigh 189 pounds, and Daddy left because you got an F in sex!”
